摘要： A direct current motor is provided with a switch which may be rotated in opposite directions to control the direction of operation of the motor. Power is supplied to the split ring commutator of the motor by means of spring-biased brushes passing through openings in an insulating plate positioned between the commutator and the brushes. Rotation of the brushes over the surface of the insulating plate will effect a change in the position of the brushes through the openings in the plate and will thus effect a reversal in the operation of the motor.

摘要： A rail brush assembly for an electric motor having a commutator, comprises a brush, a spring, a pair of rails and at least one detent for retaining the brush on the rails. The brush has a groove on each of a pair of opposite sides. The rails are disposed in the grooves for guiding the brush to the commutator with the brush being freely slidable along the rails within a predetermined range of motion. The spring is arranged to urge the brush along the rails towards the commutator of the motor and is attached to an end of the brush remote from the commutator. The detent is formed between the spring and at least one rail to limit the range of movement of the brush along the rails.

摘要： A multi-brush cage assembly for a subfractional horsepower electric motor has two brushes 22, 23 received in separate chambers 24, 25 of the cage and urged by springs 26, 27 towards a commutator 15 of the motor. An L-shaped changeover lever 30 is located on a pivot 33 between the chambers and keeps one brush 23 retracted until the other brush 22 has worn out.

摘要： The invention relates to an electric motor for motor vehicles, in particular a direct current low-power electric motor, comprising a housing (3) and a brush assembly holder (7) which holds at least two brush holders (21) with brushes (22) attached thereto, such that the brushes (22) are in biased contact with commutator (23), wherein the brushes (22) are pre-ground corresponding to commutator (23).According to the invention, the brush assembly holder (7) is movably supported in relation to the commutator (23) and a limit stop (13) fixed relative to the housing is provided in order to position the brushes (22) accurately on the commutator. Consequently, further production tolerances, for example when pushing the plug-in electronic module into the housing of the electric motor, have no effect on the accuracy with which the brushes are positioned.The invention further relates to an electric drive unit for motor vehicles, in particular for window lifts or designed as an electric actuator unit, comprising the electric motor referred to above.

摘要： Detailed are brush assemblies for electric motors. The assemblies may include retention springs or other mechanisms designed to bias brushes away from surfaces of commutators during assembly of the motors. Such retention mechanisms additionally may be fitted into cavities in associated cover plates following motor assembly. The cover plates further may include tabs which, in use of the motor, assist in supporting side surfaces of the brushes and in orienting the plate relative to a corresponding brush card.

摘要： It is to provide a brush-equipped motor enabled to be used for a long time without performing operations and without interruption even when the brush wears out. When a rotor is caused to perform a turning operation, cam projections similarly start to perform a turning operation. Then, an abutting part, at which each of the cam projections contacts with a spring piece part of a corresponding one of the first brushes, gradually moves to an end of the first brush. Thus, the spring piece part of each of the first brushes is gradually and elastically deformed in a direction in which brush bodies come away from a commutator. When the turning operation continues still more, an end of each of the second brushes comes off a corresponding one of the cam projections, so that the brush bodies thereof contact with the surface of the commutator.

摘要： A positive-side brush and a negative-side brush are held by a motor frame and contact the sliding-contact surface of a commutator. A displacement member switches the state of one brush connected with a starting power source from an ON state in which the brush contacts the commutator to an OFF state in which the brush is separated from the commutator or vice versa. The displacement member comprises a slide rail holding the brush movably, a return spring which returns the brush to the OFF state, and a push button which is manually operated to press the brush against the commutator so as to turn on the brush. A starting electric circuit can be opened or closed by operating the push button.
